Title: Softening or plasticising regenerated cellulose pellicles
IPC: D06M13/148
Filed: 1944-05-31
Abstract: Regenerated cellulose pellicles, including sheets, tubes, bands and capsules, are softened by impregnating them with an aqueous solution of glycerol and a hygroscopic alkali metal salt of an organic acid. The softening agent may contain 1 to 3 parts of glycerol to 1 part of hygroscopic salt and the proportion of softening agent to the material softened may be from 8 to 25 per cent.  The glycerol may be produced by synthesis, as a by-product of the saponification of fats, or by the fermentation of molasses or sugar solutions.  The hygroscopic salt may be a salt of sodium, potassium, or lithium with acetic, propionic, butyric, valeric, lactic, tartaric, citric, salicylic, or acetylsalicylic acid. Hygroscopic acetates, particularly potassium acetate, are preferred.  Regenerated cellulose film may be passed while in the wet gel state through an aqueous solution of glycerol and potassium acetate, the concentration of the mixture being 3.5 to 5 per cent by weight of the solution.  After drying, about 15 per cent of softener is left in the film.  In examples, sheets, films, or sausage casing tubes of regenerated cellulose are softened by treatment with aqueous solutions of glycerol and potassium acetate or sodium lactate.  The treatment may be applied to undried water-swollen products in order to prevent shrinkage before use.  The softening liquid may contain additional softening agents such as ethylene glycol, diethylene glycol, alkylolamines, sorbitol, or urea.

Title: Improvements relating to the securing together of sheets of paper
IPC: B31F5/02
Filed: 1924-04-28
Abstract: 215,019. Vßg¾, P. V., and Paldy, J. April 28, 1924. Paper bags and the like, making.-In apparatus for closing and binding together sheets of paper by passing them under pressure between two toothed wheels, the wheels 1,2. Fig. 1, are constantly pressed towards one another by the resilient action of a lever. The wheels are provided with sharp, wedge-shaped teeth and with correspondingly-shaped tooth spaces between the teeth, and may be relatively adjustable and radially yieldable, preferably under the action of co-operating springs of different natures. The lower wheel may be rotated by a crank 26, Fig. 1, and mounted in fixed bearings in a frame 25 attachable to a table, whilst the upper wheel 2 is freely mounted on a stud 27 eccentric to a shaft which is rotatably mounted in the frame and which is slotted to engage a blade spring 29. The spring 29 may be adjusted by a set-screw 28 to vary the pressure between the rollers 1, 2 or may be attached to the free end of a spiral spring. The papers are guided by a sheet-metal feed-table 33 tangential to the wheels with one edge bent up and are braked by a blade spring at 35, pressing them against the table 33. In a modification, one wheel may be mounted in a fork 40, Fig. 5, on a spring or other blade 41 forming a two-armed lever co-operating with a fixed abutment 42 and with an adjustable set-screw 43 or an adjustable spring. The wheels may have teeth inclined to their axes. Specification 3441/06 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises other modifications and applications to making paper bags and to tear-off closures. The wheels may be provided with corresponding cleaning-rollers 44, Fig. 1 (Cancelled), or with rotary cylindrical brushes to remove paper dust from the teeth 3. The bearings of one roller may be fixed and those of the other may slide in guides under the action of a spring. In another method avoiding great pressure on the papers, the superposed papers are folded as shown in Fig. 2 (Cancelled), and the fold 4 may be stiffened by corrugating transversely to the fold. The folding may be facilitated by passing the paper through engaging rollers 8, 9, Fig. 6 (Cancelled), of the section shown before passing to folders comprising a guide rib 53, Fig. 8 (Cancelled), and a funnel-shaped groove 50 of dove-tail crosssection, the front ends of the folders being rounded to prevent tearing. The groove may be formed in a single member or may be adjustable by pivoting the side cheeks 18, 19 to the base 20 and adjusting them relatively to each other by right-hand and left-hand screw spindles 15, 16 and an operating lever 17. The rib 53 may be adjustable relatively to the base 20. The papers may pass through the rollers 8, 9 and through the groove 50 and then through corrugating rollers. This subject-matter does not appear in the Specification as accepted.

Title: Swivel pipe joints and method of preventing freezing thereof
IPC: F16L27/08
Filed: 1961-03-23
Abstract: 898,244. Swivel pipe joints. CHIKSAN CO. March 23, 1961 [April 4, 1960], No. 10566/61. Class 99(1). A swivel joint, e.g. for handling liquefied gases, has members 22, 24, which define a primary fluid flow path through the joint and a secondary flow fluid path branching from the primary path and arranged to direct fluid against relatively movable interior parts of the joint to flood those parts with fluid so as to exclude air from between the parts and thereby prevent the formation of condensate thereon which might freeze and render the joint inoperative. As shown, the member 24 is provided with apertures 80 which allow passage of fluid to ball bearings 68, 69 and to a circumferential flow passage 48, a radial fluid passage 65 being also formed between the ends of the members 22, 24. Secured to the end of the socket 34 of the member 22 are spacers 54, 58 and a split retaining ring 60 having radiallyextending drain notches 60a, and intermediate resilient and deformable metal seals 52, 56 and a dust seal 59, the latter being deformed and maintaining a sliding seal with the inclined wall 102 of the flange 98. The inner portion of the spacer 54 has a number of axially extending apertures 84 in which are slidably mounted plungers 86 pressed by springs 94 against a pressure ring 90 which forces the seal 56 in engagement with the radial surface 96 of the flange 98. To reduce sliding friction the seals 56, 59 may be coated with molybdenum disulphide; alternatively, the seals may be of a plastic compound such as "Kel-F" or " Teflon " (Registered Trade Marks) or a plastic compound incorporated with metal seals. Instead of ball-bearings, needle or sleeve-type bearings may be used, and the passage 65 may be sealed or obstructed by a bearing, the circulation of the fluid from the bores 22a, 24a, of the members 22, 24 to the bearings being by way of flow passages providing communication between the bore 22a, the passage 48 and the passages 80.

Title: Improvements in and relating to the reduction of iron oxide
IPC: C21B13/00
Filed: 1956-04-12
Abstract: 838,067. Reducing iron ores. HYDROCARBON RESEARCH Inc. April 12, 1956 [April 12, 1955], No. 11227/56. Class 72 A process for the reduction of iron oxides in a bed maintained in a fluidized state by a hydrogen - containing gas comprises heating the gas to a temperature above that at which the particles of the bed would agglomerate, passing it in indirect heat exchange through the bed, and passing the gas, now cooled to a temperature below that at which the particles would agglomerate, through bed to maintain the fluidized state and reduce the iron oxides. As shown, the gas, heated to a temperature above 1000‹C., may enter the reducing chamber 12 through a pipe 10 near the top of the fluidized bed and pass through pipes 11, so that some of its heat is given up to the bed, leave the pipes at the bottom of the chamber, and pass upwardly through the bed. In a modification, Fig. 2 (not shown), the gas may enter at the bottom through pipes enclosed in tubes closed at the top end, the gas passing downwardly in the annular spaces between the pipes and the tubes into a space below the bed and finally upwardly through a perforated plate supporting the bed. The process is preferably operated at a pressure of 350-450 p.s.i.g. and temperature of 700-1000 ‹C. and may be either a batch process or a continuous process. The waste gas, after removal of contaminating water, may be recycled with fresh gas which may contain methane, nitrogen, argon, carbon oxides, and water vapour but should have an average molecular weight not exceeding 10 and the water vapour content, which depends on the temperature and pressure, should be maintained at a low value, e.g. at 400 p.s.i.g. it should not exceed 0.2% by volume Specification 751,105 is referred to.
